Alternative Methods for Calculating Off-Cycle Credits Under the Light-Duty Vehicle Greenhouse Gas Emissions Program: Applications From Volkswagen Group of America, Inc.
EPA is requesting comment on applications from Volkswagen Group of America, Inc. (``Volkswagen '') for off-cycle carbon dioxide (CO<INF>2</INF>) credits under EPA's light-duty vehicle greenhouse gas emissions standards. ``Off-cycle'' emission reductions can be achieved by employing technologies that result in real-world benefits, but where that benefit is not adequately captured on the test procedures used by manufacturers to demonstrate compliance with emission standards. EPA's light-duty vehicle greenhouse gas program acknowledges these benefits by giving automobile manufacturers several options for generating ``off-cycle'' CO<INF>2</INF> credits. Under the regulations, a manufacturer may apply for CO<INF>2</INF> credits for off-cycle technologies that result in off-cycle benefits. In these cases, a manufacturer must provide EPA with a proposed methodology for determining the real-world off-cycle benefit. Volkswagen has submitted an application that describe methodologies for determining off-cycle credits from technologies described in their application. Pursuant to applicable regulations, EPA is making these off-cycle credit calculation methodologies available for public comment.
